On 25 July 1984, Soviet cosmonauts Svetlana Savitskaya and Vladimir Dzhanibekov performed a 3-hour 30-minute spacewalk on the outside of the Salyut 7 space station, during which they performed welding, brazing and metal spraying.

They used a hand-held electron beam for their metal work, which had been designed specially for this work over 10 years.
